Hi all,I have configured a gensub record to output a string array but this doesn't work.I set the following genSub fields: FTVN:STRING NOVN:12 in my process function I do the following: sprintf ((char*)precord->valn, "Defect String 1"); sprintf ( (char*)(((char**)(precord->valn))+1), "Defect String 2"); When I execute the IOC, the output is the following: epics> dbgf IOCASTE-TST:ProcessDynamicModbusTable.VALN DBR_STRING: DefeDefect String 2 the second string has overwritten the first one. It seems that there only one string thanks in advance for your help.
